VENTING
OVEN VENTING FOR FIRE DECK MODELS FD-9660 & FD-11260
It is never appropriate to use “B vent” in any part of an exhaust system connected to this oven� The venting system should be
inspected and cleaned at least every 3 months or as necessary, more frequently with wood fired applications� Wood Stone Ovens
with model numbers containing a suffix -W (wood) or -CL (coal) must be vented as a solid fuel appliance in accordance with NFPA
96� All combustion products and cooking vapors from the Wood Stone Fire Deck 9660 and 11260 vent through a 12-inch ID flue
collar located on the top of the oven, above the doorway�
Due to the dangers of creosote buildup and of sparks entering the duct, these models must be vented separately from all other
kitchen equipment or in such a manner as is acceptable to the authority having jurisdiction� The Wood Stone customer support
staff is available to answer any questions concerning installation and venting of the oven� Solid fuel exhaust contains creosote
and other substances that accumulate in ducting, creating a risk of fire� The rate of accumulation will vary with respect to flue gas
temperature, wood type and moisture content� Frequent, regularly scheduled, thorough flue cleaning is the best way to minimize
the risk of flue fires� Wood Stone recommends cleaning and inspection at least monthly on any ventilation system
serving solid fuel equipment.
THE FOLLOWING ARE THE MANUFACTURER’S REQUIREMENTS FOR VENTING THE
FD-9660 AND FD-11260 OVENS. THERE ARE TWO OPTIONS SHOWN BELOW.
1. A Listed building heating appliance chimney, also listed as a grease duct connected directly to the oven flue collar and
provided with a power ventilator listed for restaurant appliance exhaust and rated for operation at a minimum of 350°F (450
°F for units burning solid fuel)� Use a stack or curb mounted fan� Wood Stone does not recommend the use of an in-line fan�
A field built grease duct installed and constructed according to the requirements spelled out in NFPA 96, or the International
Mechanical Code may also be used�
A static pressure of -0�1 inches water column (-0�14 inches water column for models burning solid fuel) is necessary at the
oven flue collar to ensure that gas temperatures do not exceed 300 °F (450 °F for solid fuel models) at the fan inlet� This
measurement may be taken by inserting the probe of the magnahelic gauge through the oven doorway, upwards to the oven
flue collar� The CFM required to attain this static pressure will be approximately 600 CFM for gas only models� Models burning
solid fuel will require approximately 750 CFM�
If using direct connect, it must be on its own duct system� Do not tie a duct direct connected to an oven into a duct system
serving hoods due to balancing and potential code issues� Also note that if fire suppression is required, a Type 1 hood should
be used due to the higher flue temperatures associated with the direct connect type of install�
NOTE: Double door ovens (models ending in -DD), have two flue collars� Both must be connected and a static pressure of
negative 0�1 inches must be maintained at each collar�
OR
2. A listed Type 1 Exhaust Hood or one that is constructed and installed in accordance with NFPA 96 and all relevant local and
national codes� Solid fuel burning equipment must be vented in accordance with NFPA 96� Wood Stone offers eyebrow-type
hoods designed specifically for Wood Stone ovens� Wood Stone does not recommend the use of an in-line fan�
NOTE: Double door ovens (models ending in “-DD”), have two flue collars� Both must be vented with a Listed Type 1 exhaust
hood�
VERY IMPORTANT! Refer to the exhaust hood manufacturer’s instructions for additional inspection, maintenance and cleaning
information� Wood Stone Recommends that YOU SUBMIT VENTING PLANS TO LOCAL CODE AUTHORITIES BEFORE PROCEEDING
WITH INSTALLATION�
